Even though it was released in Japan in May, the Arai RX-7 RR5 has yet to go on sale in North America. It has, however, just reached Europe, where it's been renamed the RX-7 GP and additional details of its features have been revealed. Although it looks similar to the RX-7 Corsair, which it replaces, the new range-topper receives a revised shell, new vents and additional safety features.
The first thing you'll notice will be the addition of a five-position
adjustable air wing on the back of the helmet. Arai claims, "The Air
Wing reduces drag, turbulence and buffeting resulting in more comfort
and additional top-speed. Especially when braking from high speeds when
the riders rise to a more upward position, helmet buffeting is a common
problem. With the Air Wing, buffeting is greatly reduced, resulting in
better riding concentration. The Air Wing also improves top speed
thanks to the superior aero dynamical properties of the ventilation
vents on the RX-7 GP."
That new ventilation system is apparent in the new intakes located on
the raised upper vents and the exhausts located behind the ears. Arai
claims this new design both flows more air and reduces noise.
The new shell is both larger at the bottom, to make it easier to put
on, and stronger thanks to a peripheral belt along its base and a
revised "super fiber" construction that the company claims is stronger
in anti-compression and anti-stretch as well as being more rigid than
There's also a wider visor aperture in the new shell for improved
peripheral vision and spoilers on the new visor that help reduce wind
noise. This means previous generation visors will be incompatible with
the GP and vice versa.
Like the Arai Tour X3, the GP gains Arai's emergency release cheek
pads, which allow paramedics to remove them (and the neck roll) at the
pull of a tab, allowing a riders head to be removed from the helmet
with decreased stress on the neck.
While Japan-spec RX-7 RR5s are available on eBay, Arai makes its helmets in different shapes for different markets (the thinking goes that Asians have different skull shapes to Europeans). So we'd recommend waiting until the helmet goes on sale here before buying one. Hopefully that'll take place soon.
